Functions ¶

func Walk ¶

func Walk(root string, walkFn WalkFunc) error

Walk is a wrapper for filepath.Walk which can call multiple walkFn in parallel, allowing to handle each item concurrently. A maximum of twice the runtime.NumCPU() walkFn will be called at any one time. If you want to change the maximum, use WalkN instead.

The order of calls is non-deterministic.

Note that this implementation only supports primitive error handling:

- no errors are ever passed to walkFn;

- once a walkFn returns any error, all further processing stops and the error is returned to the caller of Walk;

- filepath.SkipDir is not supported;

- if more than one walkFn instance will return an error, only one of such errors will be propagated and returned by Walk, others will be silently discarded.

func WalkN ¶

func WalkN(root string, walkFn WalkFunc, num int) error

WalkN is a wrapper for filepath.Walk which can call multiple walkFn in parallel, allowing to handle each item concurrently. A maximum of num walkFn will be called at any one time.

Please see Walk documentation for caveats of using this function.
